X is something you could factor out or 4x
Answer: B
Step-by-step explanation:
2/3 x 2/1 =4/3
Note: √a * √a = a
√a * √b = √ab
(√2 + √10)² = (√2 + √10)(√2 + √10)
= √2(√2 + √10) + √10(√2 + √10)
= √2*√2 + √2*√10 + √10*√2 + √10*√10
= 2 + √20 + √20 + 10
= (2 + 10) + (√20 + √20)
= 12 + 2√20
√20 = √(4 *5) = √4 * √5 = 2√5
= 12 + 2√20 = 12 + 2(2√5)
= 12 + 4√5
Answer:
114,688
Step-by-step explanation:
the previous term is multiplied by 4 to get the next term.if you continue with this sequence you would eventually get 114 688
From the z-table and at p67 or 0.67 (the decimal values in the table),
Z =0.44
